Which of the following is NOT one of the 8 major food allergies?

Barley is not classified as one of the 8 major food allergies that are well-recognized, such as milk, eggs, peanuts, tree nuts, fish, shellfish, soy, and wheat. These major allergens are outlined by the Food Allergy Research and Education organization (FARE) and are most commonly associated with severe allergic reactions. Barley, while it can trigger a reaction in individuals with celiac disease or gluten intolerance, is not typically recognized as a major food allergen that leads to anaphylaxis or severe allergic responses like the other listed options.
